EARTHED.
Warning: Wiring external to the unit must
be carried out by an appropriately
qualied person to current IEE regulations
for Electrical Installations and any local regulations
which apply. Wiring should be completed in exible
conduit.
Heaters are for use with 230V, 1N, 50Hz supplies.
The method of connection to the main electricity supply
must:-
- facilitate the complete electrical isolation of the heater(s)
that will prevent remote activation of the heater during
servicing.
- be in a readily accessible position adjacent to the
heater(s).
- serve only the heater(s).
- have a contact separation of at least 3mm in all poles.
See section 2.4 or the accompanying wiring diagram for
the heater electrical connections.
Warning: Lockout reset is by a switched

Reference must be made to Section 1.2 to ascertain the
electrical loading of the unit(s) being installed so that
cables of adequate cross-sectional area are used for
the electrical installation. The length of the conductors
between the cord anchorage and the terminals must be
such that the current carrying conductors become taut
before the earth conductor if the cable or cord slips out
of the cord anchorage. All external controls must be of an
approved type.
